Pack lunch like it just came out of the fridge.

The Mueller Ultra-Insulated Lunch Bag uses four layers of high-density insulation and a seamless leakproof interior to keep cold food cold for up to 8 hours and hot meals warm for up to 4 hours. The roomy 5.8-quart compartment fits a full lunch - sandwich, salad, sides, drinks - or up to 9 soda cans. Built to commute, travel, and survive the 3 PM meeting room.

Why busy professionals, students, and parents choose this lunch bag:

  • Stays cold 8 hours, hot 4 hours - Four-layer high-density insulation with a thermal aluminum lining holds temperature through a full workday or school day.
  • Leakproof seamless interior - Hot-press sealed seams (no stitched leak points). Spills wipe clean with a damp cloth - no soaked liner, no lingering smell.
  • Roomy 5.8-quart capacity - Fits 9 soda cans, a full salad bowl, sandwich containers, snacks, and an ice pack, all at once.
  • Four organization pockets - One inner mesh pocket, two side mesh pockets, and a front zippered pocket for utensils, napkins, keys, and phone.
  • Carry it your way -Padded top handle, adjustable shoulder strap, and a clip loop. Wear it crossbody, sling it on a backpack, or grab and go.
  • Built to last - 600D Oxford cloth exterior resists splashes, tears, and abrasion. Double-zip closure pulls smooth even with one hand.
  • Food-safe interior - BPA-free, FDA-compliant lining is safe for direct contact with food, drinks, and ice packs.
